THE SOLID STATE REACTION BETWEEN TRIS(ETHYLENEDIAMINE) CHROMIUM(III) COMPLEXES AND ALKALI METAL HALIDES AND THIOCYANATES.
Abstract
The solid-state reaction between /Cr(en)3/X3 (X = Cl(-), Br(-), I(-) and SCN(-) and NH4X (X = F(-), Cl(-), Br(-), I(-) and SCN(-)), KX (X = Cl(-), Br(-), I(-)), and NaSCN, was studied by high temperature and dynamic reflectance spectroscopic techniques from ambient to 225C. The reaction product, in most cases, was cis-/Cr(en)2Y2/X, where Y and X are the same or different anions, depending upon the matrix material employed. In an ammonium salt matrix, the ease of anion coordination was: F(-) > SCN(-) > Cl(-) > Br(-); in an alkali metal salt matrix, the order was: SCN(-) > F(-) > Cl(-) > Br(-). The 'thermal matrix' method described appears to offer a useful new route for the synthesis of bis(ethylenediamine) chromium(III) complexes. (Author)
